10kV Indoor Sf6 Gas Insulated Ring Main Unit Switchgear

General

XGN15-12 unit type metal enclosed ring network switchgear is a compact and expandable metal enclosed ring network switchgear that uses FLNO-12 SF6 load switch as the main switch and the whole cabinet is air insulated, suitable for distribution automation. The utility model has the advantages of simple structure, flexible operation, reliable interlocking, convenient installation, etc. Satisfactory technical solutions can be provided for various applications and different user requirements.

The main switch of XGN15-12 unit type metal enclosed ring network switchgear adopts the FLN36-12, FLN48-12 SF6 load switch produced by our company, or the SFG SF6 load switch produced by WEIFAN GROUP. VS1, VD4/S, ISM vacuum circuit breakers or HD4/55 SF6 circuit breakers can also be equipped according to the needs of users. The load switch and circuit breaker can be operated manually or electrically, and the distribution automation function can be realized after the electric operating mechanism, PT, CT, FTU and communication device are selected.

Main purpose
XGN15-12 unit type metal enclosed ring network switchgear is applicable to the power system with rated voltage of 12kV and rated frequency of 50Hz, and is widely used in industrial and civil cable ring networks and power supply terminals.
